Cytotoxicity and chemical profiles of Bai-Shao, Gan-Cao, and SG-Tang. (a) MTT cell viability assay of HEK-293 and SH-SY5Y cells after treatment with Bai-Shao, Gan-Cao, and SG-Tang (0.1~1000 μg/ml) for 24 h. To normalize, the relative viability of untreated cells was set as 100%. The red line represents 50% viability. (b) HPLC analysis of Bai-Shao, Gan-Cao, and SG-Tang. Chromatographic patterns (230 and 250 nm) show peaks compatible with paeoniflorin and ammonium glycyrrhizinate. Also shown below are chemical structures of paeoniflorin and ammonium glycyrrhizinate and the relative amounts (in % and mM) of these molecules in Bai-Shao, Gan-Cao, and SG-Tang (0.5 g/ml).
